# Contraction Timer ＆ Tracker vs Waves

The clearest difference is review sentiment: Waves at 100% against Contraction Timer ＆ Tracker's 68%. Waves also leads on rating (5.0 vs 4.6). Contraction Timer ＆ Tracker's advantage is ratings volume (50K vs 6) and monetization model (free with in-app purchases vs paid). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Contraction Timer ＆ Tracker sells 6 in-app purchases, starting at $1.99 per 7 days and Waves sells 10 in-app purchases, starting at $1.99 per 6 months. Whichever you choose, the download price is not the number that matters.

Waves holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Contraction Timer ＆ Tracker has 50K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 68% of Contraction Timer ＆ Tracker's written reviews are positive against 100% of Waves's.
